I'm trying (not really but it sounds nicer) to understand how that information is supposed to change my reply....

Again, what did you miss about all systems?

Not just mirrorless vs MFT, ASPC or FF or whoever or whatever.

It was about improving the AF on all systems.

How do I make it any plainer?

He says that it is about all systems but he provides nothing to substantiate this in the DSLR world. Nikon already offers several other DSLRs with better AF so if you want better than the D7100 then problem solved... buy something else. Unless you are trying to tell me that a majority of people buying the D7100, X-T1, E-M1 are still not going to be satisfied with AF on par with the Nikon D4 which I find laughable. The only valid point in his article is that mirrorless AF needs to improve regardless of Thom trying to make it appear otherwise. How do I make that any plainer?
